Josh is described as having straight, blond hair.
he has a sister named Veronica who has straight blond hair like him. he seemed not to like her very much when he was younger saying she was ugly.
he has a dad who dad worked away from home until Josh "ran away" and Veronica died and he had to stay closer to his wife to comfort her
not much is known about his mom besides the fact she was very upset after losing both her children.
he seems like a pretty nice guy, he was the first to approach and make friends with Dathen and it is assumed he tried to complete their map as a birthday present before he was killed.
